39-551 25.4mm Dia. x 100mm FL; Coated; ZnSe Plano-Convex Lens BBAR 8-12µm

The 39-551 is a Plano-Convex Spherical Lens, part of the extensive catalog of optical elements at 3DOptix. This lens, sourced from Edmund Optics, boasts a diameter of 25.4mm and a focal length of 100mm, designed for use with a wavelength of 10600nm.

The lens is constructed from ZnSe (Zinc Selenide) material, specifically identified as 'znse connolly' in the material ID. This material is known for its excellent transmission properties in the infrared region, making it suitable for various applications in this spectrum.

The lens features a BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces. This coating, identified as 'edm dbbarl znse 812', is specifically designed for use with wavelengths between 8 and 12µm. It significantly reduces surface reflections, thereby enhancing the overall transmission of the lens.

The geometry of the lens includes a thickness of 1.92mm at the edge and 2.5mm at the center. The inner and outer radii are both zero, indicating a plano-convex shape. This shape is often used in optical systems to focus or collimate light, making this lens a versatile component in various applications.

The lens is currently in stock, according to the vendor's website, and further information can be found at the provided weblink.
